Abstract
The invention discloses a resource-utilization and pretreatment integrated system for storage and transportation oil sludge and a pretreatment method for the storage and transportation oil sludge. A pack breaking machine is used for breaking packs of oil sludge packed by woven bags; the oil sludge is transported to an oil sludge pool for storage; after being fully diluted, the oil sludge is transported to a helicoid transporting device; the when the helicoid transporting device is used for transporting the diluted oil sludge into a shaker separator; the shaker separator can be used for separating out solid particles with large diameters and impurities; the diluted oil sludge with the solid particles with the large diameter and the impurities being separated returns back to an oil sludge homogenizing reactor after passing through a vibration separating pump; small solid particles with small diameters can be transported to the shaker separator by a small solid particle transporting pump; a mixture in the oil sludge homogenizing reactor is transported into a heat exchange device by a cleaning pump, and returns back to the oil sludge homogenizing reactor after being circularly heated and the pretreated oil sludge is finally transported to a three-phase separation device. According to the system and the method, the functions of unpacking, screening for removing impurity, cleaning, slowly-heating, homogenizing, continuous transporting and the like of the oil sludge can be realized.
Description
technical field [0001] The invention belongs to the technical field of resource reuse, and in particular relates to an integrated pretreatment system and a pretreatment method for resource utilization and storage of oil sludge. Background technique [0002] Storage and transportation sludge is one of the main industrial solid wastes produced during the transportation and storage of crude oil. Its composition is complex, mainly composed of water, hydrocarbons, minerals and other impurities. It is an extremely stable suspension emulsion liquid system. According to the National Hazardous Waste List, the storage and transportation of oil sludge is a hazardous waste (No. HW08), and its main pollutants are petroleum and heavy metals. If not disposed of properly, these pollutants will cause harm to groundwater, marine ecological environment and marine life. At the same time, the storage and transportation sludge has a high oil content and high utilization value. Therefore, unifie...
